My Wlan does not get connected, only showing networks, but internet connection works only with RJ45. I am hoping for some sort of summary answer to solve this kind of problems in a generic way. I have listed below some command that may help to solve the problem. Yes, I try to solve the current problem at hand but I would also like to know the essential commands to debug this kind of probs in the future.
